Who among the following made experiments on Weber's Law and Sensory discrimination?
A. John Locke
B. Weber Guster Fechner
C. David Hume
D. Helmhotz
Answer: Option B
Solution (By Examveda Team)
Weber's Law and sensory discrimination are important concepts in psychology that explore how we perceive differences in sensations.This question asks who conducted experiments related to these concepts.
Option A: John Locke is a famous philosopher, but not directly associated with experiments on Weber's Law.
Option B: Weber Guster Fechner is the correct answer. Gustav Fechner built upon the work of Ernst Weber, and together their research led to the formulation of Weber's Law, which describes the relationship between the magnitude of a stimulus and the just noticeable difference in that stimulus.
Option C: David Hume is another influential philosopher but is not linked to these specific experiments.
Option D: Helmhotz made significant contributions to science, but his primary focus wasn't on these particular experiments on Weber's law and sensory discrimination.
Therefore, the experiments on Weber's Law and sensory discrimination were primarily conducted by Weber and Fechner.

Weber's Law is a fundamental principle in psychology and psychophysics that describes the relationship between the physical magnitude of a stimulus and the perceived difference in magnitude.
*Weber's Law Formula:*
ΔI / I = k
- ΔI = the just-noticeable difference (JND) in intensity
- I = the initial intensity of the stimulus
- k = the Weber fraction (a constant value)
Weber's Law states that the minimum amount of change in a stimulus that can be perceived is proportional to the original intensity of the stimulus. This means that as the intensity of a stimulus increases, the amount of change required to notice a difference also increases.
*Examples:*
1. *Weight:* If you're holding a 10-kg weight, you might notice a 1-kg difference. However, if you're holding a 100-kg weight, you might need a 10-kg difference to notice a change.
2. *Loudness:* If you're listening to a quiet sound (e.g., 10 dB), a small increase in volume (e.g., 5 dB) might be noticeable. However, if you're listening to a loud sound (e.g., 100 dB), you might need a larger increase in volume (e.g., 20 dB) to notice a difference.
Weber's Law has important implications for various fields, including psychology, neuroscience, engineering, and design.
